FOREWORD
(This foreword is not part of this Standard.)
This document is an addendum to TIA-968-B, Telecommunications – Telephone Terminal
Equipment – Technical Requirements for Connection of Terminal Equipment to the Telephone
Network. It was developed to provide a new sub-clause on test conditions for requirements for
testing wideband and narrowband analog telephones for out-of-band emissions.
This addendum was produced by Subcommittee TR-41.9, Technical and Administrative
Regulatory Considerations. It was developed in accordance with TIA procedural guidelines, and
represents the consensus position of the Subcommittee, which served as the formulating group.
It also received the concurrence of Engineering Committee TR-41, Performance and
Accessibility for Communications Products.
The leadership of the TR-41.9 Technical and Administrative Regulatory Considerations
Subcommittee acknowledges the written contributions provided by the following individuals in
the development of this addendum.

1. SCOPE
This addendum provides changes to TIA-968-B, Telecommunications – Telephone Terminal
Equipment – Technical Requirements for Connection of Terminal Equipment to the Telephone
Network. Clause 2 adds new informative references. Clause 3 adds a new sub-clause 5.1.9.4
specifying the use of an acoustic stimulus signal when testing analog telephones having
electroacoustic transducers for live voice input for compliance with out-of-band emissions and
in-band longitudinal signal requirements. All other clauses in TIA-968-B are not affected.
Additions to the text are shown underlined. Words that appear in underlined italics in this
addendum are intended as instructions to the reader.
2. ADDITION TO INFORMATIVE REFERENCES
Add the following reference to Clause 2:
6. IEEE Std 269-2010, IEEE Standard Methods for Measuring Transmission Performance of
Analog and Digital Telephone Sets, Handsets, and Headsets
3. ADDITION OF NEW SUB-CLAUSE
Add new sub-clause 5.1.9.4 as follows:
5.1.9.4
Voice terminal equipment containing electroacoustic transducers for live voice input,
including recording devices, shall comply with the limitations with a real male speech
acoustic signal as specified in IEEE Std 269, set to a level of -4.7 dBPa, applied to the
electroacoustic transducers.
